Audio Grade Ethernet Cable

A question for technically savvy individuals... Please do not send me the AI-generated answer.  I have tried and it gives me two drastically different answers depending on how I ask... 

Q: It is known that Cat 6 can transmit data at speeds up to 10 Gbps using a maximum bandwidth of 250 MHz, while Cat 8 supports speeds up to 25–40 Gbps with a maximum bandwidth of 2000 MHz. So, for transmitting 10 Gbps, Cat 6 operates at around 250 MHz. If I use a Cat 8 cable to transmit data at the same 10 Gbps rate, what frequency will the Cat 8 cable operate at? Same frequency of 250 MHZ or higher and how high will it be?

Thank you, @cleeds.  So if the frequency is data speed dependent, why some people complains about cat 8 is noisier and generates more EMI/RFI? 

@cleeds  I never imply that you have made that claim.  Thank you for the clarification.
